What happen when the capillary rise occur in a tube of insufficient length? My teacher told me that hR = constant where h is height and R is radius of sphere of which the curved surface of meniscus firm a part. She also told me that if h become less so R has to increase so radius of meniscus has to be large. I didn't really get what she's meant. If we take a capillary tube of height h and put it in water then, the tube become filled with water till height h. Now if we break a tube to make it of height less than h then will water flow out?
